As a part of its technique to ramp up companies based mostly on its rising next-generation structure, Taiwan Cellular (TWM) has revealed that checks it has carried out with main comms tech agency Nokia has achieved the world’s first New Radio Service Aggregation (NR CA) by combining spectrum within the 700MHz (n28) and 3500MHz (n78) spectrum bands.

TWM offers cellular, fixed-line, cable TV and broadband companies. Claiming to be a forerunner in digital innovation, the corporate mentioned that it’s working to reposition itself as a next-gen know-how agency main the following revolution in sectors of telecommunications, web, media and leisure, and e-commerce by implementing a 6C technique encompassing protection, convergence, content material, channel, cloud and CSR.

TWM formally launched 5G companies on 1 July 2020, launching a rebranding initiative to reinvent itself into an organization advocating the model spirit of Open Attainable.

In deploying the know-how wanted to attain these goals, provider aggregation can mix frequency bands for larger charges and is designed to extend protection, ship superior community capability and maximise the spectral effectivity of 5G networks.

In June 2021, TWM chosen the Finnish comms know-how agency as its sole provider of its 5G community in a three-year framework contract. The deal covers 5G RAN, 5G Core and 5G IMS together with its newest AirScale Radio Entry merchandise. Nokia has been a long-standing associate of TWM and is supporting the corporate in its efforts to execute its Tremendous 5G technique, which is concentrated on sustainability and digital transformation. 

The companions mentioned that their trial, which befell in a 5G standalone (SA) community atmosphere, paves the way in which for TWM to ship market-leading 5G experiences to its clients with enhanced connectivity and capability.  

The profitable trial was carried out with AirScale 5G SA structure in TWM’s business 5G community, and mixed two spectrum bands – frequency division duplex (FDD) in 700MHz (n28) and time division duplex (TDD) in 3500MHz (n78) – that are extensively adopted in 5G networks worldwide.

Decrease frequency band FDD offers wide-coverage space enhancing cell edge efficiency whereas TDD has a better bandwidth and capability. The corporations mentioned the mix of those spectrum bands gives enhanced capability and protection supporting a spread of 5G deployment situations, together with indoor and enhanced out of doors protection. MediaTek supported the trial by offering gear to confirm community efficiency.

“This trial is a crucial milestone as we execute our 5G technique and ship best-in-class 5G companies to our subscribers,” mentioned Tom Koh, senior vice-president and chief know-how officer of know-how group Taiwan Cellular.

“Combining SA with NR CA, our 5G consumer expertise is raised to the following stage whereas the utilisation of our spectrum property and 5G networks are maximised. We’re happy with our partnership with Nokia as we proceed to advance deployment and construct a thriving 5G ecosystem.”

Mark Atkinson, senior vice-president of radio entry networks PLM at Nokia, added: “We’re delighted to have accomplished this profitable trial with our trusted associate, Taiwan Cellular. Aggregating spectrum is an environment friendly strategy to allow enhanced protection and capability. This profitable trial highlights how cellular operators with comparable spectrum allocation can obtain comparable outcomes.”
